The lithium battery factory is divided into two parts:
If you make a battery, the contents of the battery are harmful to people's health. It is not recommended to go. You should bring a gas mask or a mask to work.
If it is a bag, it has no effect on the body (individual stations need to be exposed to organic solvents).
The so-called radiation refers to the phenomenon that radio frequency waves generated by high-frequency oscillation of the circuit are emitted into space. Radiation with a certain frequency and intensity has an effect on the body. The batteries used are generally chemical reactions and physical changes, and there is no radio frequency, so there is no radiation.
All objects in nature always transfer heat to the outside world in the form of electromagnetic waves as long as the temperature is above absolute zero. This way of transmitting energy is called radiation. The energy released by an object through radiation is called radiant energy, or simply radiation.
Even you yourself are constantly radiating energy to the outside world. So, don't be nervous when you hear radiation. It can be said that radiation is everywhere. As a human being, it has evolved for millions of years and has natural resistance to common radiation. When charging, that kind of radiation energy can be ignored, so don't think much.
The production process of lithium battery production line and whether it will cause pollution (gas, water, soil) in the process.
As far as the production process of lithium batteries is concerned, lithium batteries will not be polluted by toxic heavy metals.
Of course, this concept is relative. Compared with lead-acid and nickel-chromium batteries, it has little pollution and no heavy metal pollution. But it is definitely harmful to the environment.
Electrode materials, electrolytes and solvents may be contaminated: during the pole piece manufacturing process, the domestic mainstream lithium ferrous phosphate system or even ternary system is not seriously polluted.
Of course, the ternary system may still have some lithium cobaltate pollution. For example, cobalt, manganese and nickel are all heavy metals, but they are relatively environmentally friendly. Among them, lithium ferrous phosphate is the most environmentally friendly.
For the rest, except the above-mentioned material pollution, the solvent in the injection is mainly cyclic/chain carbonate or carboxylate. Solute is mainly lithium salt lithium hexafluorophosphate, and additives are mainly film-forming additives, flame retardant additives, conductive additives and additives for improving low-temperature discharge.
The whole process of pollution is also good. Of course, if chemicals are not controlled, they will certainly pollute the environment. As for the final packaging and molding, the pollution is even smaller.
Of course, the recovery of lithium cobaltate and ternary system is necessary, after all, it contains heavy metals. Compared with other batteries, lithium ferrous phosphate does not produce any toxic and harmful metal elements and substances such as lead, mercury and cadmium except the internal electrolyte, so the pollution is relatively small.
However, the substances in waste lithium-ion batteries will still cause heavy metal nickel-cobalt pollution (including arsenic), fluorine pollution, organic pollution, dust and acid-base pollution.
Electrolyte of waste lithium-ion batteries and its conversion products, such as LiPF6, LiAsF6, LiCF3S03, HF, P20 1, and solvents and their decomposition and hydrolysis products, such as DME, methanol and formic acid. , are all toxic and harmful substances, so waste lithium-ion batteries need to be sent to qualified places for unified treatment, and don't throw them away at will.
There are also many kinds of lithium batteries. Common lithium batteries include lithium ion batteries and lithium polymer batteries. Lithium-ion batteries are mostly wrapped in stainless steel casing, which is relatively safe.
Like tinfoil paper, the outer packaging of lithium polymer battery is easy to be damaged, and it is easy to cause combustion after being damaged, because lithium is a very active metal, and contact with air will cause combustion.
